Fraction and decimal
b) A computer can download 3 by 10 parts of a movie file in 1 minute. After
downloading the file for 50 seconds, the internet was interrupted and after a
while, again it started downloading. If the size of the movie file was 2.4 GB,
what were the sizes of the file downloaded before and after the interruption
of the internet?​

Answer 1

Before Interruption : 0.6 GB

After Interruption : 1.8 GB

Step-by-step explanation:

Given: 3 by 10 in 1 minute, Total size : 2.4GB, Interruption at 50 sec.

Calculate data downloaded in 1 minute. That is (2.4*3)/10 GB = 0.72 GB

Calculate data downloaded in 50 seconds. That is (0.72*60)/50 GB = 0.60 GB (Before Interruption)

Calculate data downloaded after Interruption = 2.4-0.6 = 1.8 GB
